Answer:
c. The placement and relationship of elements within a picture
Explanation:
Required
What composition means?
Literally, composition means the way the elements of a picture are presented. The elements in this case constitute all lines, shapes, dots, pattern and many more.
You will notice that some of these elements will be placed over one another, some side by side, some far from one another.
So, composition means the way these elements are displayed.
<em>Hence, option (c) is correct.</em>
Answer:
Abstraction is the process of removing or taking away certain characteristics to reduce or hide several very important characteristics.
In OOP (Object Oriented Programming), to increase efficiency and reduce complexity, a programmer hides certain vital data about an object. This is abstraction in programming.
For further clarification, a programmer ensures that the name given to an entity makes sense and most importantly, that it carries relevant aspects, and non essential parts are not included.
